I do, but I haven't the cash to invest in it all, especially because it wouldn't just be the tv. I'd have to upgrade to a 4K Blu-Ray player, get a new 4k compatible receiver, plus new cables. And then I've been reading about how all 4K UHD Blus put out so far are actually 2K masters upscaled on disc with 4K encoding, and then some have HDR? That didn't sound right to me, but I kept reading it in different places. Sounds like it's currently not worth the investment, even with streaming services offering at least partial 4K content. But dem new LG OLED 4Ks is so damn shmexy.
Not that I'm any sort of industry expert or anything, but I kind of see 4K being the generation that the physical format officially dies with the major studios, in this country at least. Niche and specialty studios will probably continue to put out Blus and DVDs for a long time, but I don't see Iron Man 14 coming to 8K Blu home video in the US. So it's a bit of a conundrum of both not wanting to miss out, but also not wanting to invest in a partially supported format. I feel like, if I have the cash in the next year or two, and there's much better support, I'll throw a few grand on a credit card for a system upgrade. Apart from that, I might just stick with ye old 1080p plasma til it dies.
